// MainActivity :

public class MainActivity extends AppCompatActivity {

    private TabLayout tabLayout;
    public ViewPager viewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);

        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);

        View headerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE))
                .inflate(R.layout.custom_tab, null, false);

        tabLayout.getTabAt(0).setCustomView(linearLayoutOne);
        tabLayout.getTabAt(1).setCustomView(linearLayout2);


        tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {

                if (tab.getText().equals("ONE")) {

    }

    private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFragment(new OneFragment(), "ONE");
        adapter.addFragment(new TwoFragment(), "TWO");

        }

        @Override

            return mFragmentList.size();
        }

        public void addFragment(Fragment fragment, String title) {
            mFragmentList.add(fragment);

    }

}

回答1:

HI you can easily achieve custom tab with tab layout , Try this one

  public void setupTabView(){
    for (int i = 0; i < tabLayout.getTabCount(); i++) {
        tabLayout.getTabAt(i).setCustomView(R.layout.custom_tab);
        TextView tab_name = (TextView) tabLayout.getTabAt(i).getCustomView().findViewById(R.id.txt_tab_name);
        tab_name.setText("" + tabNames[i]);
    }
}

And make one drawable file with name custom_tab

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

     <TextView
         android:id="@+id/txt_tab_name"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:gravity="center"
         android:textSize="14sp" />


</RelativeLayout>

I copied the solution from here, Maybe it will be useful for you

 Display display = getWindowManager().getDefaultDisplay();
    int width = display.getWidth();

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

   TabHost mTabHost = getTabHost();

   mTabHost.addTab(mTabHost.newTabSpec("tab_test1")
           .setIndicator((""),getResources().getDrawable(R.drawable.mzl_05))
     .setContent(new Intent(this, NearBy.class)));
   mTabHost.addTab(mTabHost.newTabSpec("tab_test2")
           .setIndicator((""),getResources().getDrawable(R.drawable.mzl_08))
     .setContent(new Intent(this, SearchBy.class)));
           mTabHost.setCurrentTab(0);
           mTabHost.getTabWidget().getChildAt(0).setLayoutParams(new
             LinearLayout.LayoutParams((width/2)-2,50));
      mTabHost.getTabWidget().getChildAt(1).setLayoutParams(new
                 LinearLayout.LayoutParams((width/2)-2,50));

You can try another code tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 50;

回答3:

Create Custom tab layout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp">

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/tv_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@drawable/tab_text_color_selector"
        android:textSize="@dimen/medium_text"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/tv_count"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_marginStart="4dp"
        android:background="@drawable/badge_background"
        android:gravity="center"
        android:textColor="@color/colorPrimary"
        android:textSize="@dimen/medium_text"
        android:textStyle="bold"
        android:visibility="gone" />
</LinearLayout>

tabTitles = new String[]{getString(R.string.main_tab_call), getString(R.string.main_tab_chat), getString(R.string.main_tab_contact)};

  private void setupTabIcons() {
    for (int i = 0; i < tabTitles.length; i++) {
        mTabLayout.getTabAt(i).setCustomView(prepareTabView(i));
    }
}


private View prepareTabView(int pos) {
    View view = getLayoutInflater().inflate(R.layout.custom_tab, null);
    TextView tv_title = view.findViewById(R.id.tv_title);
    TextView tv_count = view.findViewById(R.id.tv_count);
    tv_title.setText(tabTitles[pos]);
    return view;
}

Use Below Code .It is have two option. (i) Create custom TabLayout (ii) Change custom tablayout text color

(i) Custom TabLayout

 <TextView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/tab"
android:layout_width="match_parent"
android:textSize="15sp"
android:gravity="center"
android:textColor="@color/txtbox_text_color_darek"
android:layout_height="match_parent"
/>

Source code is:

        TextView tabOne = (TextView) 
        LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabOne.setText("KPIs" + " ");
        tabOne.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.alert_gray, 
        0);
        Objects.requireNonNull(tabLayout.getTabAt(4)).setCustomView(tabOne);

(II) Change Color

     private void custom_tablayout_select_unselected_four(final TextView tabOne) {

     tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            if (Objects.requireNonNull(tabLayout.getTabAt(4)).isSelected()) {
                tabOne.setTextColor(getResources().getColor(R.color.text_color_darkblue));
            } else {


      tabOne.setTextColor(getResources().getColor(R.color.txtbox_text_color_darek));
            }

        }

        @Override`
        public void onTabUnselected(TabLayout.Tab tab) {
            // tabOne.setTextColor(Color.GREEN);
        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {
            // tabOne.setTextColor(Color.GREEN);
        }
    });

}

Below code custom tablayout in android.

public class MainActivity extends AppCompatActivity {
    private TabLayout tabLayout;
    private ViewPager viewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        viewPager = (ViewPager) findViewById(R.id.viewpager);
        createViewPager(viewPager);

        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
        createTabIcons();
    }
    private void createTabIcons() {

        TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabOne.setText("Tab 1");
        tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_dash26, 0, 0);
        tabLayout.getTabAt(0).setCustomView(tabOne);

        TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabTwo.setText("Tab 2");
        tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_category, 0, 0);
        tabLayout.getTabAt(1).setCustomView(tabTwo);

        TextView tabThree = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabThree.setText("Tab 3");
        tabThree.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_order, 0, 0);
        tabLayout.getTabAt(2).setCustomView(tabThree);
    }

    private void createViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new Fragment1(), "Tab 1");
        adapter.addFrag(new Fragment2(), "Tab 2");
        adapter.addFrag(new Fragment3(), "Tab 3");
        viewPager.setAdapter(adapter);
    }

    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        public void addFrag(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }
